IMPROVEMENT IN' CURB-GRINDERS.

The Schedule referred to in these-Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, C. W. TERPENING, of Geneseo, in the county ofHenry,and State of Illinois, have invented a new and improvedCurd-Grinder; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference My invention relates tomachines for grinding curd,

and mixing the same with salt; and

It consists in an improved arrangement and combination of Vparts for theaccomplishment of said object, as hereinafter fully described.

A, inl the drawing, represents a frame made of wood, or other suitablematerial, of two longitudinal side bars a, and a suitable number ofcross-bars, b b.

This -frame is to be fitted upon a vat, B, so that it can be firmlylocked and readily removed. The-crossbar b at one end has, therefore,downward-projecting arms c with inwardly-projectingpins el that iit intothe sides of the vat, while ou the opposite end of the frame isasuitable wedge, key, set-screw, or cam, e, for locking the frame overthe ends of the vat, as shown.

One of the end cross-bars b may be made adjustable longitudinallyon thebars a., so as to adapt the frame to vats of different length.

O represents yone ofthe grinding-disks. It is made of wood, or othernon-corrosive material, and ismounted upon a wooden or other shaft, D,which has its bearings in one end cross-bar b of the frame, and inanother movable cross-bar, b1, of the same. he shaft D can move with thebar b1, and slides then through the end cross-bar b.

E represents the other grinding-disk. It is fastened to a plate, j',which has a horizontal notch, whereby it is fitted upon a cross-bar1),lof the frame A, a rubber scribed.

spring, g, being interposed between the front edge ot the bar h2 and theplate f.- y

The disk E supports a hopper, F, and is ou the sides an d bottomsurrounded by a forward-projectiu g flange, h, that embraces the disk G,as shown;

The lowerend of the plate f is, by a rod, yi, braced toa cross-bar, b,ot' the frame.

Upon the faces of the disks C E are fitted the grinding-bars ll, whichmay be alternately long and short, as sho\vnor of other suit-ablearrangement. They are bevelled to one side, and form sharp edges on theother.-

Vhen rotary motion in the right direction is, by

vhand or otherwise, applied to the shaft D, the bars of thevtwo diskswill be moved lwith the hevelled edges toward each other, and not withthe sharp edges, as in ordinary mill-burrs.

It is not so much theobject to cut the eurd as it is to agitate andblend it with the salt.

The spring g allows the disk E to vibrate during the rotation ot' thedisk G, so as to make the hopper selffeeding.

rlhe prepared grinders through au aperture, m, of the disk E.

The curd to be treated is put intol the hopper, and the shaft is thenrevolved, thereby grinding and mixing the contents of the hopper.

The ilange h serves to retain the curd between the grinders as long asthe sameis not discharged through the aperture m.

The cross-bar b1 can be adj usted more or less distant from the end ofthe frame, by means of wedges ln, or otherwise-,so as to hohl the disksmore or less close together.

Haring thus described-mvinvention,

What L claim as new, and desire to secure by Let ters Patent, is Y Thecombination of the longitudinallyadjustablev disk C, oscillating disk E,hopper F, tlange h, and spring g, with the frame A, all constructed,arranged, andy operating substantially as herein shown and de- C.
